Fig. 10 is a detail fragmentary ers ective vicwofthe mold and one of the pallet elders or clamps. Fig. 11 is a 4 5 perspective view, partly in section, of a post formed by a mechanism constructed in aceordance with the present invention. Fig. 12 is a longitudinal sectional view of a post constructed in accordance with the present invention and showing peculiarly-constructed fastening means for securing wires or strands in position. Fig. 13 1s a fragmentary longitudinal sectional view of a post constructed in accordance with the present invention and showing another embod ment of the fastening means; and Fig. 14 is a similar view of the post, showing another-embodiment oft-he fastening means for securing a board to a post.

Referring to the drawings by referencenumerals, 1 1 designate the standards-or uprights of the support or framework of the mechanism. Each u right is preferably in-- tegral with a base 2, w 'ch base 2'is preferably curved tlirou hout its length for forming feet 3 3. Incline braces 4 i are integral with the base 2 and the standard 1. The standards 1 are connected by a horizontal brace or beam 51 Each standard is provided with a longi tudinally-extending slot 6. Positioned upon opposite sides of each oi the standards 1 are vertically-adjustable horizontal mold and pallet supporting brackets or holders 7 and 8, respectively. Each of the brackets 7 and 8 is similarly constructed and is also similarly secured to a standard 1. Each bracket comprises a horizontal body provided with avertical portion extending at right angles to said body. The vertical portion of the bracket is I apertured for receiving any, ordinary fastening meansas, for instance, a bolt-and-nut structure 9for securing the bracket in an adjusted. position. Thebraekets 7 ands are adjustable substantially the entire length of the standards 1, and this adjustability oi said brackets is desirable, for the reason that differant-sized molds may be used upon the support constituted by the standards 1, and it is desirable to adjust the brackets 8 for accommodating pallets of different thicknesses.

The upper end of each of the standards 1 is provided with a horizontal apertured stud or lug 10. A mold or matrix 11 is provided upon the upper portion of its rear side or wall l2 with preferably a pair of horizontal arms '13. These arms 13 are flush with the upper horizontal edges of the mold, and upon the outer end of each oi these arms there is formed a horizontal apertured extension or lug 10. Suitable fastening means-as, for instance, a pin or pintle 14is os-itioned within the apertured. portions of t ie lugs 10 and 10 for securing the arms 13 to the standards 1. The mold 11 comprises the rear side or wall 12, bottom 15, hinged door or section 16, and ends 17. The bottom is longitu dinally inwardly bulged or depressed, as at 18, and in the bulged portion 18 of the bot tom 15 alined apertures 19 are formed. These apertures 19 are provided for permitting the insertion of an implement for forming apertures in the ppst or molded article while said post is in a green or Wet state.

The door or hinged section 16 is provided -55 its upper longitudinal edge with a rein- 2b "of the hinge for the same.

forcing rib or bead 20, which is also true of the ends 17 and the rear side 16. This strengthening-rib 2O materially increases the strength of the mold-body. Formed upon [the lower longitudinal edge of the hinged Lsecti'on 1.6 is a cylindrical portion 21, which .is preferably solid. This cylindrical portion 21 of the hinged section constitutes a portion The portion 22, Figs. 8 and 10, is provided with a concaved groove 23, within which is seated the cylindrical portion 21 of the hinged section 16. Near each end of the cylindrical portion 21 of the door 16 an internally-threaded socket 24 is formed, Fig. 7. Each of the ends 17 is provided with a lug 25, which lug 25 is pro vided. with an aperture 26. Threaded bolts 27, which are provided with. unthreadcd por- 3o tions near their heads, are threaded. into the recesses 24. The hinged section 16 is only secured to ends 17 by means of the threaded structure 24 of the cylindrical portion 21 and the bolts 27. The cylindrical portion 21 is braced intermediate its ends by means of reinforciing 'or strengthening lugs 28, Figs. 1

5 and 9, Each of these strengtheningdugs 28 "is preferably cast upon the bottom. of the' 40, end, which fits snugly mold. and is provided with a curved outer against the periphery of theportion 21. By means of these lugs the hinged section is strengthened intermediate its ends, which is desirable when the plastic materialfias, for instance, cement--is in #5 the mold and is being tamped or packed.

The peculiar construction. of the hinged sec- I tion or door 16 prevents the hinge from becomingclogged or choked with any foiuign substance, as the. portion 21, working in the concavekl portion 253, Fig. 8, produces a continuous surfaceexposed upon the inside of i the mo'ld whether the section or door 16 is in its closed or opened position.

It is desirable to securethe lunged section 16 in alcloscd'position, and for this reasonT have provided a locking device for accomplishing this result. This locking device comprises horizontal housings 29, carried by the ends of thexscrdion 16. Each of the 6o housings 29, Figs. 1 and 6, is provided with a -removable cap tl't), Fig. 1.

housing a slidablefibolt 31 is positioned. A spring 32 is positioned within each of the housings and upon each of-the bolts. 31. A

seam? upon the outer face of the hinged section 16. A lever 34- is fulcrunied, as at 35, upon the lug or extension 33. Each of the bolts 31 is pivotally connected, as at 36, to a rod 37. The inner ends of the rods 37 are pivotally connected, as at 38, to the lever 34. One of the rods 37 is connect ed to the lever 34 above ed to said. lever below said fulcrum, By swinging the lever 34 upon its fulcrum in the direction of the arrow, Fig. 6, the springpressed bolts 31 will be withdrawn from the apertured lugs or studs 39, formed upon the sides 17 of the mold 11. These lugs 39 are formed upon the upper edge of the sides and are provided with apertures registering with apertures formed in the outer ends of the housings when the hinged section is closed. When the spring pressed bolts are withdrawn from the lugs 39, the section 16 may be swung upon its hinge for permitting the removal of the mold off of the pallet 40, Fig. 5, without injury to the molded article 41. The spring-pressed bolts 31 constitute locking means for securing the hinged section 16 in a closed position, which locking means is actuated by manually-operated. lever means.

I em loy clamps or holders 42, carried by the mo (.1 or matrix 11, for securing the pallet 40 upon the mold while the same is being moved to its dun'iped position, Fig. 4. In Fig. 4. the hinged section is shown in a closed position, and said clamps and holders 42 are shown. in their normal position for holding the pallet 10 against the reinforced edges of the mold 11. Each clamp 42, Fig. 10, is pivoted upon a lug 13, which is formed integral upon the rear side .12 of the mold 11. The clamp is provided with a substantially straight body 44 and a right-angled extension 45. The right-ai'igled extension is provided with a rev'oluble threaded member or screw 46. The member 46 is provided at its lower end with a plate 48, which plate 48 is preferably disleshaped. After the mold has been. filled with plastic material and said material tampcd the reinforced edges of the mold and the clamps Within each 42 are positioned for placing the horizontal extension or portion 45 parallel with the pallet. The screws are then adjustedfor causing the plates 48 to grip the pallet 40 for positively securing the same clamped against the mold until the plates 48 are moved away from said pallet 40 prior to the positioning of the mold in its normal vertical or upright position. It will therefore be seen that the mold is provided. with pivotally-mounted .clamping means for securing a pallet in position thereon.

In Fig. 5 the clamping means is swung away from the pallet and the section 16 is in upper end with a suitable grip 4.7 and at itsv pallet 40 placed upon the vertical central stud 33 is formed integrally 6 its fulerum 35, while the other rod is connect- ICC "51 are formed in the post.

an open position. The mold 11 may be detached from its support by removing the pins or fastening means 14, and another mold of a different size" may be positioned upon the support. The horizontal brackets can be quickly adjusted to accommodate a differentsizedmold, which is likewise true of the brackets 8 for receiving a pallet that is of different thickness to the one last used. The mold 11 is preferablyof greater width at one end than at itso )posite end. The body of the mold tapers t roughout its entire length for producing tapering posts. (Depicted in Fi s. 12 to 14.) y

n Figs. 11. to 14 I have shown the structure of a )ost which is molded by my mechanism. he post comprises a body 49, Which is preferably reinforced by longitudinally-extending wires or strands 50. These strands or wires are placed in the body of the mold while the lastic material s being placed therein. 'li iansverselywxtending apertures tapers throughout itslength and is narrowest at its front or wire-engaging faces 02, while it is Widest at the rear face 58. The rear end of the apertures 51 terminates in a longitudinally-extending groove 54. It is to be noted that the bulged portion 18 of the mold produces this longitudinal groove 54 in thc post. Within this groove the fastened ends of wires 55 and 56 are positioned, this groove forming a guard or protection of these twisted or fastened ends.

In Figs. 11 and 12 the Wire 55 is looped around the strands 56, as at 57, and the wire 55 is drawn taut, thereby clamping the loop 57 at the narrowest end of the tapering aperture.

In Fig. 13 the fastening means for securing the wires 56 to the post comprises a continuous strand 58, which is threaded through each aperture and looped around each wire 56 that is attached to the post. A single wire in this instance constitutes fastening means together with the post, while in Fig. 12

I each single wire 55 secures only two strands fastening means comprises a single wire (St),

to the post. It is to be noted that in each of thcsecmbodin'ients the small end of the transverse apertures 51 causes the loop 5? to fit snugly around the strand when the wires or strands which are threaded through the apertures are drawn taut. V

In Fig. 14 l have shown fastening means for securing boards 59 to the post. This which is threaded through two apertures of the post and the board, and the ends of said wire are twisted or fastened together, as at (51, within the longitudinal groove 54 of the post.
